Fox News Contributor Andy McCarthy: This Seems To Be Someone Trying To Terrorize & Scare More Than Someone Trying To Commit Mass Murder

The package bombs sent to prominent Democrats have touched off a bitter war of words in an already-combustible political environment just days before the midterms, even as the investigation continues and law enforcement officers remain on the hunt for more explosive parcels.

Former Vice President Joe Biden was the latest apparent target, with the FBI confirming two suspicious packages similar to the ones that triggered the original security scare were addressed to him in Delaware, along with one to actor Robert De Niro. A suspect has not been identified and presumably remains at large.

Andy C. McCarthy, Fox News Contributor, senior fellow at the National Review Institute and a contributing editor of National Review joined Fox News Radio's Guy Benson and Marie Harf to discuss the investigation into the package bombs sent Wednesday.

On how he is viewing the bomb scare Wednesday: I'm more interested in it from an investigative standpoint than anything else. As far as motive is concerned I always think it's a mistake to get out in front of what we know for one and number two I tend to look at this stuff as a lawyer who prosecuted terrorism cases, not as somebody who does political analysis. And I know in the world of political talking points rhetoric and all that jazz there's a lot of cavalier charges going around. In a courtroom incitement to mass murder attacks is a pretty serious thing. It's pretty serious business. Your common sense tells you that you may get riled up by somebody who is an expert demagogue, but nobody goes out and commits mass murder on account of something that they heard at a political rally and that goes for political rallies of both sides.

On why he thinks this was not someone attempting mass murder: The new information that we have is that none of the 8 or 9 detonated. The usual thing with mail bombs and package bombs is that they're rigged up in a booby trap way so that when you try to open them that's what makes them explode. They're not operating on a timer. Evidently, people opened these packages. What we're hearing in the reporting here is that these packages were handled they were opened, at least some of them not all of 9 of them, and none of them went off. The two possibilities that would be in the front of my mind as an investigator based on all that information is that we're either dealing with a very incompetent terrorist or set of terrorists, that's not an impossible, but it seems to be less likely than the other scenario, which is that we're dealing with somebody who is sending out - it's kind of in the same vein as the anthrax scare some years back and we get repetition of this from time to time too. Where people put harmless powder in an envelope or package to scare the person who is the recipient into believing that they're getting anthrax or some kind of chemical attack. I think this is probably shaping to something more like that. (7:28)

On how long the investigation might take: I think this will be quick. The last reports I've heard in the last few hours is that Florida is a place that has become of great interest to investigators and it would seem to me that if those reports are true it's the function of the fact that when you get all these device and they're intact and you have the packaging and you have the ability to do all the forensic testing and you couple that with something we have today, which I didn't have 20 years ago, which is all these ambiguous video that's all over the place. They probably have some good leads on who it is they're looking for and I would expect that they'll probably have somebody in custody pretty soon. (11:02)
